Canada is a NATO member, which means Canadian innovators can compete for defence and security funding outside of federal programs. The NATO DIANA Challenges program supports dual-use technologies—those with both civilian and defence applications—with funding of up to $300,000 per project through a competitive accelerator model.
If your company works in deep tech, advanced engineering, or applied science, this program provides access to capital, testing sites, and NATO customers.
The Defence Innovation Accelerator for the North Atlantic (DIANA) is a NATO initiative designed to fast-track dual-use innovation across member countries, including Canada. Each year, NATO publishes a set of technology challenges tied to defence and security priorities.
Selected companies enter a multi-phase accelerator program:
Funding comes with access to NATO test centres, mentors, and potential defence buyers across allied countries.
Canadian participation is allowed because Canada is a NATO member state.
Typical eligible applicants include:
Most successful applicants are early-stage or growth-stage innovators with strong technical teams. There is no published revenue cap, but projects must clearly fit NATO’s challenge areas.
The NATO DIANA application process is centralized and competitive.
Step-by-step overview:
Challenge call opens
NATO publishes annual DIANA challenges on its official portal.
Online application submission
You submit a technical proposal explaining:
Evaluation and selection
Applications are assessed on:
Accelerator participation
Selected companies receive funding and enter Phase 1, with the option to progress to Phase 2.
If you want to quickly filter international and defence-focused programs suitable for Canadian applicants, tools like GrantHub’s eligibility matcher can help.
Your proposal must address one of NATO’s published challenge themes. Current focus areas include:
Projects with clear civilian market potential and defence relevance are the most competitive.
1. Submitting a purely civilian use case
DIANA requires dual-use relevance. If defence applications are vague, your application is unlikely to pass screening.
2. Applying with low technical readiness
Concept-only ideas struggle. NATO looks for technologies that can be tested and validated within the accelerator timeline.
3. Ignoring NATO challenge language
Using generic innovation language instead of NATO’s published priorities weakens alignment.
4. Underestimating competition
DIANA is highly competitive across all NATO countries. Strong technical detail and clear impact matter.
Q: Can Canadian startups apply to NATO DIANA Challenges?
Yes. Canadian companies are eligible because Canada is a NATO member state.
Q: How much funding does NATO DIANA provide?
DIANA provides $100,000 in Phase 1 and up to $300,000 total if a project advances to Phase 2.
Q: Is NATO DIANA funding repayable?
No. The funding is non-repayable, but it is generally considered taxable income for Canadian businesses. Confirm with your accountant.
Q: What types of technologies are the best fit?
Deep tech solutions with defence and civilian applications, such as autonomy, energy systems, advanced communications, and data-driven technologies.
Q: How competitive is the program?
Very competitive. Applications are reviewed across all NATO countries, with selection based on innovation, defence relevance, and scalability.
NATO DIANA Challenges are not a fit for every business, but they can be powerful for Canadian companies building dual-use technology. The key is matching your project to the right challenge at the right time.
GrantHub tracks active international and Canadian grant programs, including defence and innovation funding. Reviewing which programs match your business profile can help you decide whether DIANA—or another funding option—is right for your next stage of growth.
